How to fix?

Upgrade SLES:15.3 qemu-chardev-spice to version 5.2.0-17.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-chardev-spice package and not the qemu-chardev-spice package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

QEMU 5.0.0 has a heap-based Buffer Overflow in flatview_read_continue in exec.c because hw/sd/sdhci.c mishandles a write operation in the SDHC_BLKSIZE case.
